6 essential satellite services that critical infrastructures depend on By Dr Jordan Plotnek, Lead Partner for Critical Infrastructure at Anchoram Consulting

t is well known that critical infrastructures on Earth rely heavily on space systems to function effectively, however the exact nature of this dependency is less commonly understood. Quantifying this mysterious link is an important step to navigating supply chain risk management for critical infrastructure operators and enabling a mission-focused security and resilience strategy for satellite service providers. With this in mind, let’s dive into the top six satellite capabilities that critical infrastructure sectors need to continue delivering these essential services to society.
Communications Satellite services provide essential communication links for terrestrial critical infrastructures. They enable voice, data, and video transmissions, especially in remote or hardto-reach areas where terrestrial communications may be limited. Satellites support communication networks for various sectors, including emergency services, national defence, transportation, utilities, and public safety. Satellite services also bridge the connectivity gap in areas with limited terrestrial internet infrastructure or for assets on the move, such as trains, trucks, ships, and aircraft.

Positioning, Navigation, and Timing Many critical infrastructures heavily depend on systems like the Global Positioning System (GPS) for precise positioning, navigation, and timing (PNT) applications. PNT satellites provide accurate location data that is used in sectors such as transportation, emergency response, military, and utility management systems. Continuous access to a single source of time is also vital for critical infrastructures that cover large geographical areas and those whose integrity depends on accurate time stamping. Precise timing requirements are crucial for electric grid synchronisation, telecommunications, and financial systems, with potential implications including economic loss, reduced safety and security, and loss of human life.
Weather Monitoring and Forecasting Satellite-based weather monitoring systems play a vital role in the protection of terrestrial critical infrastructure. Weather satellites provide real-time and continuous observations of atmospheric conditions, allowing for accurate weather forecasting and emergency preparation. This information is crucial for sectors like aviation,
